10 Claims.

The present invention relates to rolling mills and particularly to avsystem thereof for handling made-up coils orbundles as they are beingAdelivered at short intervals from a group of bundle coilers thatreceive, coil-bundle and deliver the hot rolled output from the rolls.

A further purpose is to pull the bundles along a slideway by thesuccessive dogs of a conveyer and to speed up each bundle to unloadingarms having an angularly movable bed, the bed in its bundle receivingposition sloping downwardly fromthe discharge drums, and to angularlyreciprocate the bed upending, and retracting it, during periodsintermediate its recept of successive bundles from the drums forcharging the successive bundles upon the preferably horizontal receivingarms of a` carrier.

A further purpose is to use each dog of a conveyer first to pull abundlealong the slideway to a discharge drum and then to limit the forwardmovement oi the bundle as it slides forward to the inclined receivingvbed of an unloadingr device.

A further purpose-is to locate the axis of a four-armed bundle carrierand theline 0f travel of bundles to thefcarrier in a common verticalplane.

A furtherpurpose is to use a common drive for a conveyer and forunloading drums receiving and unloading bundles from said conveyer.

A further purpose is to provide a swinging .frame which receivesbundles, oneat a time and to unload them upon a transfer mechanismthrough an intervening pusher pivoted to the arm.

A further purpose is to'coordinate the operations of thesecondconveyer,of a bundle unloader and of a bundle carrier, using the conveyer todeliver the bundles one at a time to the unloader for one-at-a-timedelivery to the carrier. Preferably the conveyer, unloader, and carrierare operated by meansof individual limit switch motors, associatingthestarting switches of the unloader andcarrier motors respectively withthe stop switches of the conveyer and unloader motors.

A further purpose is to provide novel and efficient mechanism fortransferring a succession of bundles from a rolling-mill conveyer to anarm of bundle carrier-for subsequent presentation to bundle transfermechanism.

Further purposes will appear in the specication and in the claims.

My invention relates not only to the mechanism involved but to methodsby which this and 55 tion and referring to other mechanism may beoperated to carry out the invention.

Describing in illustration andnot'in limitathe drawings:

It will be understood that the hot rolled products from a plurality ofrolls, not shown, deliver to any of a number o bundle-coilers inpositions Hi, il and I8, Figure la, and that neither the rolls nor thebundle-coilers are themselves the object of the present invention.

The` bundle-coilers may be of any suitable number and be located side byside'. They are intended to be shown here conventionally only, and asfour in number.

Each bundle-coile1` includes a vertically'movable stripper spider |9,20, 2|, 22 above which each bundle or coil 23, 24, 25, 25 is woundbetween inside and outside fingers 21 and 23. The fingers 21 and 23 ofeach coiler extend upwardly from and form a portion of an intermittentlymovable rotor 29, Sil, 3|, 32 individual to that coiler. In eachposition the corresponding rotor is stopped after winding a coil and thestripper spider I9, 25, 2| or 22 is then moved vertically upwardly topresent the freshly wound coil high enough to clear the ngers and infront of one of a group of discharge plungers 33, 34, 35 and 35.

The invention does not reside in the coilers nor in the mechanism bywhich the coils are discharged. The discharge plungers are operated inany suitable way by a motor not shown. The coils are hollow and aredischarged as in the prior art, being deposited upon the receivingI orinput end of a slideway 4|, extending longitudinally in the direction offeed. They are progressed on the slideway by a first conveyer 42, whichcarries them into position where their forward interior surfaces areengaged by the dogs of a second conveyer.

The bundles of the various groups upon the slideway are carried meantimeby a second conveyer 43, preferably an intermittently continuousconveyer, through successive intermediate positions to the voutputunloading (discharge) end of the slideway. Here they are fed, one at atime to speed pick-up slideway unloader drums 44, 45, which acteffectively as a unit.

At the slideway discharge point an unloader 46 pushes the bundles one ata time upon one of the arms 4l, 4B, 49, 50 of a bundle holder or carrier5|. It is shown as of four-arm turnstile type. The bundle holder orcarrier 5| moves intermittently to present its receiving arms 4T, 48, 49and 5|) successively to the bundle receiving position. As soon as onearm is filled another is presented to receive bundles. In receivingposition these arms lie in the vertical plane of the second conveyer.

The slideway for convenience is located over a pit 52 within thefoundation walls 53. These walls, along with piers 54, posts 55 andbeams 55, 5'! provide supports 58, for the two conveyers 42, 43; andfoundations 59, 50, El and B21, for conveyer sprocket support; S3 and 64for conveyer driving and timing mechanisms; 65 for the bundle holder 5|;65 for the driving and timing devices for the bundle holder; and 61 forthe means for tilting unloader 45.

The bundles are advanced bythe first conveyer by pushing for a reasonwhich will later appear. This pushing is accomplished by dogs 63, uponlinks 69 of the first conveyer 42 comprising a pair of chains l0, 1|which operate about sprocket wheels l2, 13 upon a shaft 14 in bearingsl5, 1S, and about sprocket wheels Tl, 18 mounted upon a shaft 19 inbearings 88, 8|. Either pair of sprocket wheels may be drivers and theother pair driven or idlers. As illustrated 12 and 13 are the drivers.The dogs operate in parallel slots 82, 83 oppositely olset in theslideway.

Because the rst conveyer 42 shoves or pushes the bundles from the rearof each bundle, it advances the bundles beyond the forward end of thisconveyer. This gives each bundle enough of a lead at this point so thatit can be engaged conveniently by one of the prongs 84 of the secondconveyer 43 which enters within the interior space of the bundle. Thistakes place as a link 85 carrying the prongis carried by its chain SSabout one of its sprocket wheels 8l upon shaft 88 in bearings 39, S0.

The chain of this second (in this case preferably the puller type ofchain conveyer 43 passes about a second sprocket wheel Si rigidlymounted on a shaft |69 in bearings 92, 93. As in the case of the rstconveyer, either sprocket wheel may be the driver.

The top and bottom stretches of the two conveyers are supportedappropriately at 94, and 96. Si. At an intermediate point QS in thetravel of the second conveyer the slideway is narrowed, giving access tothe bundles for inspection and facilitating here the removal of bundleswhere this is desired. i

The operations of each of the different motors may be controlled by handswitches so as to be operatively separate with or without the use oflimit switches or the controls which they exert over the operation ofother parts of the system. This applies not only to both conveyers butalso to the unloading arms and to rotation of the carrier or holdershown of turnstile type. The bundles are delivered upon the slideway infront of a dog 68.

The first conveyer is relatively short and progresses the bundles to aposition where each in turn will be picked up by one of the dogs oi thesecond conveyer.

The speed of the entire system will normally be dictated by the speed ofsupply from the mill and, intermediately, by the speed of the coiling(bundling) mechanisms and their number.

The rst conveyer is operated at a speed which will deliver each bundlein time to be picked up by the second conveyer.

The second conveyer may preferably operate intermittently because it isdependent upon the supply of bundles from the ceiling mechanisms.

As a preferred means of operating I run the first and second conveyersby separate motors 99, |09, of limit switch type having suitable limitswitches IUI, |02, connecting gearing |93, |94

and bearings IE5, |05. In order to emphasize the fact that theindividual conveyers-as well as the other mechanism describedcan beactuated independently I show hand operated starting switches |91, |08in the circuits of these two motors.

It is desirable to interlink the various mechanisms so as to continuethe operation successively after it shall have been started.

One suggested way for operating, applied to operation of the secondconveyer, is to have final operation of the bundle lift at coilerposition close the circuit of the motor operating the lateral loadingmechanism to transfer a bundle to the rst conveyer. This at the startopens the circuits of the motors oi' both conveyers. Retraction of theplunger for the lateral loading closes the circuits of both conveyers.If the second conveyer controls the rst, it would not be necessary forthis plunger movement to opennor then to close-the circuit of the firstconveyer.

The limit switch |02l of the second conveyer may not only control thesecon-d -conveyer as above so as to causefit to stop after bundle has.been advanced into position for-engagement by the second conveyer, butmay also regulate the first conveyer and of the unloading arms.

In proper sequence for discharge of bundles from the second conveyer,the second conveyer will stop after feeding a bundle and it will remainstopped and the first conveyer will consequently remain stopped untilthe bundle loading mechanism shall have reciprocated, loading anotherbundle.

'Iurning of the bundle carrying arms upon which the bundles are placedby the unloaderA may also be controlled by a limit switch |02 butpreferably is controlled through the limit switch of the mechanism whichthrows the unloader arms, In either event the intention is after one armshall have been filled to have the receiving arms revolve a quarter turnprior to the placing of a succeeding bundle upon a newly presentedholder arm.

Shaft I 09 carrying sprocket 9| carries also pick up drums 44 and 45which serve several purposes. They are spaced at I| and from adjacentparts and are larger in diameter than the body of the sprocket wheel.The bundles are carried up upon their surfaces ||2 by the secondconveyer, relieving the bundles of a part at first and then of all ofthe friction against the slideway.

Through back gearing hereinafter described the pick up drums are given aperipheral speed considerably greater than the lineal speed of thesecond conveyer, with the result that as soon as the bundles have beenpushed up upon the pick up drums far enough for the pick up drums totake over the progression of the individual bundles, each bundle in turnis drawn ahead more rapidly than moves the particular dog of the secondconveyer which previously has been dragging the bundle. This relievesthe bundles from engagement with the dog and permits the dog to becarried by its link about the adjacent cirumference by the sprocketwheel 9| without rubbing the dog against the interior surface of thebundle.

The structure is stiffened by braces ||3, |I4 between the end of theslideway and the support.

In the meantime the bundle is carried by the surfaces of the drums andis thus tilted and discharged so that its forward end slides downagainst a bumper I 5 at the lower end of unloading arms 45. Asillustrated the upper part of the bundle rests upon the surfaces of thepick up drums until-which should be immediately after-the unloading arms46 start their swing toward one of the turnstile arms.

As the pick up rolls tilt the bundle down against the bumper |I5 thereneed be-and in the illustration is-no engagement between the bundle andthe upper ends of the unloader arms nor with the segmental faces of thepushers. Friction of pick-up rolls with the bundle is then avoided bytiming which immediately swings the unloading arms 46 upward and to theleft so as to first engage the bundle from the right and beneath and tolift the bundle away from the pick-uprolls. The weight of the bundle istaken at the start by the swinging, unloading arms 46 and partly by thebumper. As the bundle reaches approximately vertical position ytheweight is a1- most all transferred to the bumper and withvsubsequentmovement of the arms 46 and the push-` `shaft ||8 is gear ers the bundleis transferred to one of the arms 41-50.- A succeeding bundle whenplaced upon the Asamearm must push the next and any additional bundlesalready on Vthe arm to before the bundle which is being mounted can betransferred. The unloading arms 46 then return to the position shown indotted lines in Figure 3 to receive the next bundle.

Mechanism by which the peripheral speed of the pick-up drums may bestepped up above that of the chain advance is seen in Figure 7, in whichat the upper end of the figure back gearing is provided suitable foreffecting the stepping up of the speed.

The shaft |09 carries a gear IIS which meshes with the gear I|1 upon aback gearing shaft IIB turning in bearings ||9 and |20. Rigid with `I2|which meshes with a gear I22 rigidly connected to the drum 44 and withthe drum 44 freely turning on the shaft |09 coaxial with gear |I6. GearI22 is keyed to a hub extension from the drum 44, opposite hubextensions of the drum turning freely on the shaft |09. Intermediatebearing metal is shown in ring |24.

Because the gear ||6 is much largerthan the gear |22 and the gear I1ismuch smaller than the gear |2|,'there is considerable increase ofspeed by the back gearing shown,` the increase of speed beingproportionate to the differences in the diameters in these respectivepairs of gears.

The back gearing shaft I I8, at the opposite end from that which carriesgears I1 and IZI, carries gear |25of the same size as gear I2! and itdrives gear |26 "mounted rigidly upon one of the hub extensions |21 ofthe pick-up drum 45 which turns freely on the shaft I 09. It will beseen that the pick-up drums, on opposite sides of the sprocket 9|,operate effectively as a unit. Bearing metal |28 may be used if desiredbetween the hubs |21 and the shaft |09.

The unloading mechanism appears in Figures 1, 2, 3, 4, 'and 6.

The arms 46 are duplicates. They are rigidly mounted on a shaft |29 andwith theshaft tilt between some such positions as are shownY inciprocating the shaft, operating through crank arm |3|, pin |32,connecting rod |33, pin |34, and rocker arm rigidly mounted on the shaft|29. Any suitable mechanism connects the rocker arm and unloading arms45. As shown, both are intended to be rigidly attached to the shaft|29.4 Y

The bumper ||5 v-is adjustable along the length of the unloading arm bythe interposition between it and-the bracket I 36' of a variant quantityof lagging |31 according to the diameter of in Figure 3, the interior ofthe bundle will t over the nose |33 'of that turnstile arm 41`50 uponvwhich the bundles are being placed, without undue friction in placingthe bundle.

With the front faces upon the appropriate arm so that further swingingmovement of the unloading arms te the left The exactpoint l'to which thebundle will come and the question of whether the inside ofthe bundleshall be level with the top of the carrier arm when the engagement withthis arm takes place will be subject to variation according to thewishes and policy of the user and obviously can be varied for the samesize of the bundle 5 by altering the lagging and can be made to suitdifferent sizes of bundles by the same means, lifting the interior ofthe bundle to any predetermined height along the length of the unloadingarms.

The unloading arms are in Figures l and 5 and in side elevation 2, 3,and 6.

Each unloading arm notv only itself swings but carries at its outer enda pivoted pusher shoe, 1 the two pusher shoes being alike. The unloadingarms 45 at the upper ends are extended diagonally upward and rearward togive position for shafts |40 upon which the pusher shoes are pivoted.Each pusher comprises, as illustrated, side frame members |4| joinedacross the end by a cylindrical pusher wall |42, forming a sector whichpresents an arc shaped pusher face at |43. The center of the arc is theaxis of the pivot shaft |40;

Each pusher face is adapted to engage with the rear face of a bundlewhich is being handled and to push the bundle to the left and upwardlyas the arm 46 swings. The pivotal engagement of the pusher permits thesector to swing so thatV there is rolling engagement only between 'thepusher face and the rear of the bundle. l

The sectorial pushers are shown in cross-section in Figure 4 and in sideelevation in Figures 3 and 3c. ln Figure 4 fragmentary portions of thepick-up drums appear to the right and left and the sprocket wheel withits chain is located in the center within protecting walls |44, |45,spaced at |45. The sectorial pushers lie between these walls and thepick-up drums. Their pivot shafts or pins turn within bushings |41, |48supported by the walls of bores |49, |50 in the hubs of the respectivearms 45. Continuations |5|, |52 of the arms carry stops |53 reinforcedby rims |54. The stops limit the outward swing of the pushers by endwalls |55. Inward swing is restricted by shoulders |55, one upon eacharm. Laterally adjacent stops |53 are facing ribs |51, |51 whichnormally perform no function but which afford support against excessivelateral thrust upon the pushers.

The turnstile carrier or holder for the bundles as shown, Figures 1, 2,3 and 8, is mounted about a vertical post |58. The post |58 is rigidlymounted in bores |59 and |65 of a metal stationary base |52. This postforms a xed axle cr bearing member about which the carrier or holder 5|is turned by motor |53 controlled by limit switch |54. The motor drivesshaft |55 through coupling |55. The shaft is connected to the turnstileor holder 5| through gears |51 and |68. Shaft bearings are shown at |59,|15.

The rotary carrier or holder 5| is supported by bearings |11 and is heldagainst tilting movement by lateral bearing |12. A

The switch interlinkage between the second conveyer and the unloadingarms must be such that the arms lie back in receiving position at thetime the second conveyer delivers its foremost bundle upon the pick-updrums 44 and 45 that in turn tilt the bundle to and deliver it upon theunloading arms 45.

If the unloading arms be not immediately engaged by the bundle except atthe lower end of the bundle adjacent the bumper, it is quite deshown intop plan View in Figures sirable that the unloading arms be tilted assoon after the bundle has been placed upon them as possible in order toavoid rubbing friction between the pick-up drums and the bundle.

One of the carrier or holder arms must be opposite the bundle at thetime the unloading arms act. They place each bundle in turn upon the endof a carrier arm and each `as placed is effective to shove any bundlesalready on the carrier arm further back upon the arm, up to the timewhen this carrier arm holds its intended full load.

The timing and switch -connection are such that when the last unloadingarm movement takes place, and after the unloader arms have retracted,the carrier or holder is rotated by rotation of gear |58 to a distancesufficient to bring an empty -arm in position to receive the succeedingbundles; and one carrier or holder arm at a time is filled or partially'lled with bundles and turned to position for discharge of these bundlesas another empty carrier or holder arm is brought to position.

The linkage may be direct cr not. For example, the successive operationsof the unloader arms and carrier or holder arms need not be linked upwith the closest moving parts but in some cases can be operated by someother member within the train of operation.

It will be evident 'that the use of pushing prongs on the rst conveyerpermits the bundles to be shoved far enough ahead of the first conveyerso that the second conveyer may have room to turn and to raise itsprongs into the spaces within the bundles, v

It will further be evident that stoppage of the rst conveyer with itsforward prongs near or at the end of its pushing stroke but before theirchains have begun to turn about their sprocket wheels, with subsequentremoval of the bundle by the second ccnveyer from contact by the first,avoids scraping of the first conveyer prongs against 'the rear faces ofthe bundles when these prongs do turn with their `chains about theirsprocket wheels. The use of the pick-up rolls at the unloadingpositionlperforms a corresponding function for the second conveyor,carrying the bundles out of contact ywith the second conveyer prongsbefore these second conveyer prongs have begun to turn about theirsprocket wheels adjacent the pick-up rolls.

It will be evident that the turning of the carrier arms can take placewhile the unloader arms 44 and 45 are retracted or partly retracted butthat if the number of `bundles to a carrier arm corresponds with thenumber of bundles loaded at a time and the second conveyer be stoppedfor loading, plenty of time can be provided for this carrierarmm'ovement during the stoppage of the second conveyer.

It will be evident that the turnstile type of vcarrier construction isquite convenient and effective but that other types of carrierconstruction could be used with part of the advantage of myconstruction.

It will be evident that friction against vthe bundle can be reducedgreatly by exact timing of the delivery from the pick-up rolls and theoperation of the unloading arms. This is accomplished by having 'theypick-up rolls tilt the bundles free from initial Contact with the upperparts of the unloading arms but into contact with the bumper on theunloader and just as these unloader arms tilt to lift the bundle awayfrom the pick-up rolls. By this timing sliding of the bundle along thelength of the unloader arms is avoided and at the same time the ybundleis lifted from the pick-up rolls in time .to relieve from rubbing of theunder surface of the bundle by lthese rolls.

As seen in Figure 2, the foremost prong upon th'e second conveyer may beused to prevent the bundle from moving unduly in a lateral direction asit tilts on the pick-up rolls. It may also act as a catch, engaging theinner rear bundle surlface to take part of the jar which would other-Wise be taken upon the bumper vor all of the jar of the tilted bundle(Figure 2).

The pivotal connection of the pushers upon the unloader arms preventssliding friction of the pushers against the faces of the bundles as thebundles are transferred to the carrier arms and at the same time arelifted by the Wedge action of the sloping ends of the carrier arms asthe bundles are forced upon these arms.

It will be evident that hand switches in all of these motor circuitspermit individual operation of these circuits either-using the handswitches alone for control of the circuits or providing the handswitches as ultimate control, to prevent operation when the .individualhand switches are open. Where the hand switches 'are used for the entirecontrol of the circuits they not only permit alteration of the sequenceof the operation, to use one of the motors out of turn but a longer timethan would be the automatic control described.

In view of my invention and disclosure variations and modiiications tomeet individual whim or particular need wil-l to others skilled in theart, to obtain 'all or part of the benefits of my invention Awithoutcopying the structure shown, and I, therefore, claim all such in so faras *they fall Within the reasonable spirit and scope of my invention.
